How To Test Flame Sensor Rod
How To Test Flame Sensor Rod. Clean the flame sensor using a. Rub the metal part (and no.
If the reading is below 5.0 microamps, you have a bad flame sensor. On a maintance check you always check for flame rectification (flame sensing). You can measure flame signal by putting your meter (capable of measuring micro amps) in line between the flame sensor and the wire that was connected to it (see picture).
Watch The Furnace Ignite You Will See Spark Or Orange Glow In Front Of One Burner And The Flame Sensor Should Be On Opposite Side, But I Have Seen Them On The Next Burner From The Igniter.
This means you need to disconnect the wire from the rod, connect one multimeter lead to the rod and connect the other to the wire you removed from the rod. Rub the metal part (and no. If still not within range try a new rod and/or tighten grounding connections.
These Components Are To Be Soldered Together In Sequence As Shown In Diagram Below (Note Component Sequence And Polarity).
You can measure flame signal by putting your meter (capable of measuring micro amps) in line between the flame sensor and the wire that was connected to it (see picture). In this hvac video, we go over the testing of the flame sensor and step by step troubleshooting processes of the flame rectification process. Ensure the furnace is properly grounded.
On A Carrier Brand 4 To 6 Ua Is Good, Below That Clean The Flame Sensor With Fine Steel Wool Or A Green Pot Scrubber And Clean The Burners.
For testing purposes, a flame detector rod bypass circuit can ba made up consisting of 2 insulated alligator clips. Putting a meter inline between the sensor and lead wire from the furnace control board allows you to read the dc. Most furnaces you will find a white wire located on the left side connecting the flame sensor to the circuit board.
A Furnace Specialist Will Test The Flame.
Your multimeter will need to be able to read dc microamps (μa) in order to test a flame sensor. Connect the multimeter to the flame sensor: If the reading is below 5.0 microamps, you have a bad flame sensor.
The Sensor Leads Into The Fire Chamber Where The Flame Burns.
Remove the flame sensors mounting screw and detach the device from the assembly. Troubleshoot flame sensor • the flame sensor in any furnace proves combustion. • disconnect the flame sensor wire from sensor.
